New Mexico spadefoot toads remain underground until rains fill low areas with water. Distinguished by eyes with vertical pupils that sit close to the top of its head and small, hard, wedge-shaped structures on the hind legs used for digging into moist soil, spadefoot toads vary in color (between gray, brown or dusky green).
The voice of the New Mexico spadefoot sounds like a fingernail running across the teeth of a comb. When threatened, the New Mexico spadefoot toad emits an odor said to smell like roasted peanuts.
